Question

Which is a larger volume, a candle with a height of 6. 3 inches and a radius of 3. 1 inches, or a candle with both a height and a radius of 3. 9 inches?

Answer 1

Explanation:

such candles are cylinders.

the volume of a cylinder is

pi×r²×height

the volume of candle 1 is

pi×3.1²×6.3 in³ = pi × 60.543 in³

the volume of candle 2 is

pi×3.9²×3.9 in³ = pi × 59.319 in³

so, candle 1 has the larger volume.
